What I mean is that ARM has has a much lower power consumption, so an ARM CPU can have much more cores than x86 even with silicon (wonder it with grafeno). What we can see today is that high number of cores reduces the efficiency, improvements on AI can change this.

Generally, the ISA doesn't really affect much - you can make a big, powerful, power-hungry aarch64 core (with a similar amount of effort as Intel put into their equivalents). And you could make a small, low-power x86_64 chip (like the Intel Atoms already do - they're certainly competitive for the equivalent ARM cores in most respects). It's more design trade offs in the implementation that decide where on that spectrum you end up. And (of course) the amount of work/investment you can afford

The instruction decoding is actually a pretty small part of today's chips, in either ARM or x86 cores.

Fine, but I don't think it's valid to compare Atom to ARM CPUs, Core m3 is a better comparison (nice performance for a 4.5W CPU).
